Hardware

This model requires no other connections. The HDMI board happily connects to both the Raspberry Pi 2 and the screen. Further this screen has a female IDC header on the back which exactly mates with the GPIO header on the Raspberry Pi 2.

This means installation is as easy as connection the screen to the Raspi and plugging in the HDMI board.

Note the power is shared as well so you only need one power supply to power the Raspi and the screen.

The GPIO header makes the necessary connections to allow the touchscreen data to be seen by the Rapsi.

Configuration

It is likely you will need to set up the screen to display properly.

The easiest way to do this is to modify the contents of your /boot/config.txt file.

I SSH'd in from a desktop machine and then used nano on the command line to edit the file:

sudo nano /boot/config.txt

Then you need to make sure your config.txt has the following lines in it to make sure the screen resolution is set:

After a reboot, that should allow your screen to display the full 800x480 with touchscreen controller available.

If you have issues, make sure you have at least 128 Mb available for graphics. You can do this by running "sudo raspi-config" at the command line and setting 128Mb or 256Mb for graphics under the memory split option.
